+         The block tap driver is an alternative to the block back driver 
+          and allows VM block requests to be redirected to userspace through
+          a device interface.  The tap allows user-space development of 
+          high-performance block backends, where disk images may be implemented
+          as files, in memory, or on other hosts across the network.  This 
+         driver can safely coexist with the existing blockback driver.
